3. I work for a camera distribution company. In reality, reflecting the existence of uncertainty in demand and lead time, we intend to determine safety inventory (SI) and reorder point (ROP) at 95% service level. As a result of the survey, the average daily sales volume (d) of cameras was 12 and the standard deviation was 4, and the lead time (LT) required to receive after ordering was 7 days. In this case, what is the safety inventory (SI) and reorder point? (If the service level is 95%, =0.05 and z=1.65, all calculations are rounded to the third decimal place.)
